Charge and Orbital Ordering and Spin State Transition Driven by Structural Distortion in YBaCo_2O_5
S. K. Kwon, B. I. Min
We have investigated electronic structures of antiferromagnetic YBaCo_2O_5 using the local spin-density approximation (LSDA) + U method. The charge and orbital ordered insulating g…

Itinerant ferromagnetism in half-metallic CoS_2
S. K. Kwon, S. J. Youn, B. I. Min
We have investigated electronic and magnetic properties of the pyrite-type CoS_2 using the linearized muffin-tin orbital (LMTO) band method. We have obtained the ferromagnetic grou…
